Deleting a group does not delete devices added to the group. Devices from a deleted group are moved to the same hierarchy level in the device tree as the deleted group.
To delete a group from the device group tree:
In the Create group tree or Select group in tree window, select the group that you want to delete.
Click the icon.
This opens a prompt window in which you can select a deletion option.
In the prompt window, click on one of the following buttons, depending on the what you want to do:
If you want to delete only the selected group and keep its child groups, click Selected only.
If you want to delete the selected group together with all of its child groups, click With child groups.
